Knife-polisher



UNITED sTATEs PATENT oEErcE;

REUBEN SHALER, OF MADISON, CONNECTICUT.

KNIFE-POLISI-IER.

Specification forming part of Letters Patent No. 5,941, dated November' 28, 1848; Reissued August To all whom t may concern i vBeit known that I, REUBEN SHALER, of Madison, in the county of New I-Iaven and State of Connecticut, have invented a new and useful Improvement on the Machine for Scouring and Polishing Knives and Forks, the construction and operation of which is described as follows, reference being had to the annexed'drawings of the same, making a part o'f this specification.

In the construction of my machine I first provide a box A Figure 1 (see the accompanying drawings). This box may be of any suitable size-say one foot long four inches wide and the sides two inches high; but the ends should be three inches higher than the sides for the purpose of forming the ends to the hopper B. The sides of the hopper are two inches high and extend from one end of the box to the other and are there` permanently fastened in a situation to have the hopper over the center of the box. The opening of the hopper at the bottom may be about one third of an inch but considerably wider at the top. The opening at the bottom of the hopper, and the thickness of the stuff of which the sides are made, should make about one inch and a half, and that whole space namely (the bottom of the hopper and the opening in the hopper) `should be covered with leather (or some other flexiblematerial) as shown at C. Through the center of this leatherdirectly in the line of the opening inthe bottom of the hopper are perforated a series of holes. Underneath the leather C is extended a second'piece of leather, D, in dimensions. exactly corresponding with the leather C, but without the series of holes. This second piece of leather extends from one end of the box to the other and being there fastened by screws or otherwise-is entirely independent of the leather C, except it is made to press against it by a series of metal springs E, E, E, E, which rest upon'a string piece F, extending the whole length of the box situated one inch below the leather D, and fastened tothe ends yof the box'A. This [FIRST PEiNTED 1913.]

string piece may be about the width ofthe leather D, and of suliicient strength to sustain the pressure of the springs E, E. The

upper ends of which press against the leather D.

(The springs are made in the.

form of those used in sofa seats.) An elastic substance like india rubber will produce the same effect. A short distance above the hopper'B, is extended a string piece H, per.v

manentlylattached to the ends of the kbox A and directly over the center of the hopper B, the upper surface of which is covered with leather.

I contemplate making these machines of` both wood and iron.

The yoperation-In polishing knives and n ished. That part of the fork which cannot be polished between the leathers is finished on the string piece II; In consequence of the motion of the. knife, between thetwo pieces of leather, the emery or pulverized brick willy pass through the holes inthe leather C, to the inward surfaces of the two strips of leather, from thence it falls into the box and may be again returned to the hopper kwhen desired.

After thus fully describing the construc-u tion and operation of my machine, .what I l claim as new, as my improvementfand desire toy secure by Letters 'Patent is- Theap-paratus within described for supplying the inward surfaces of the two pieces of leather with the scouring or polishing material used for that purpose, the operation and construction being substantially as herein set forth.
